Figure 1

Sketch of the geometrical situation and variable definitions. p1,p2are the beam profile pixel coordinates; α1and α2are the beam incidence and exit angles with related azimuth angles β and γ. d1,d2are the detector pixel coordinates, and r0=(x0), y0, z0) is the reference point of the spot center at the sample surface (a). A 2D sketch of the situation in reciprocal space for the (004) reflection is shown in (b). Therein, k1, k2are the wave vectors, q is the scattering vector, and the 2D detector (blue line) stands orthogonally to the sketch (which is the [1 1 ̄ 0] direction).
